air con is blowing warm air

[yogi]

Hello guy's
Last year my local garage recharged the air con but within a couple of weeks it was blowing out warm again,  but with this mini heat wave,  i really need it sorted

Is there a likely culprit for this,  ie seals, compressor unit,

Cheers

The system needs UV dye put into it and then leaks can be detected by UV glasses.
Any recharge place can do it.

Sounds like a leak as it worked when charged last year. Could be a seal, a condensor, evaporator, fill point etc etc.
 Plenty of things it could be so not much point in guessing.
